This book deals with colloidal systems in technical processes and the influence of colloidal systems by technical processes. It explores how new measurement capabilities can offer the potential for a dynamic development of scientific and engineering, and examines the origin of colloidal systems and its use for new products. The future challenges to colloidal process engineering are the development of appropriate equipment and processes for the production and obtainment of multi-phase structures and energetic interactions in market-relevant quantities. The book explores the relevant processes and for controlled production and how they can be used across all scales.

This book presents a comprehensive overview of the freezing of colloidal suspensions and explores cutting-edge research in the field. It is the first book to deal with this phenomenon from a multidisciplinary perspective, and examines the various occurrences, their technological uses, the fundamental phenomena, and the different modeling approaches. Its chapters integrate input from fields as diverse as materials science, physics, biology, mathematics, geophysics, and food science, and therefore provide an excellent point of departure for anyone interested in the topic. The main content is supplemented by a wealth of figures and illustrations to elucidate the concepts presented, and includes a final chapter providing advice for those starting out in the field. As such, the book provides an invaluable resource for materials scientists, physicists, biologists, and mathematicians, and will also benefit food engineers, civil engineers, and materials processing professionals.

Advances in Measurement and Control of Colloidal Processes compiles a selection of papers presented at the International Symposium on Colloid and Surface Engineering held in San Diego in August 1990. This book emphasizes practical measurement and exploitation of the principles of surface and interface science that embrace a wide range of industrial sectors. The topics are arranged according to specific measurement techniques or phenomena. The focus includes processing and characterization of aggregated materials; developments in instrumentation for monitoring and characterization of dispersions; controlled particle formation technologies; mineral and inorganic colloids-micro and macroscopic characterization methods; measurement and simulation of complex colloidal processes; and advances and problems in micron and sub-micron sizing techniques. This text is a useful reference for engineering students and industrial practitioners who conduct research on colloid and surface engineering.

Within this volume is a thorough coverage of the fundamental principles embracing modern theories of colloid chemistry applied to mineral processing. It is written in respect for Dr. J.A. Kitchener, distinguished Reader in the Science of Mineral Processing in the Royal School of Mines, Imperial College, University of London (recently retired). Dr. Kitchener's expertise in colloid chemistry has led to numerous fundamental insights and practical advances in flotation, selective flocculation, and the treatment of slimes. Colloid chemistry is inevitably involved in all aspects of mineral processing, ranging from how collectors selectively adsorb on to mineral surfaces in flotation, to the forces which control the stability of dispersions of submicron particles, as well as embracing the behaviour of hydrolyzed metal ions in solid-water slurries. The intelligent use of this information is essential in the effective design of separation processes and strategies by the mineral processor. Up to date bibliographies are included at the end of each of the 13 chapters making this volume a useful general resource for researchers, students and mineral processors.

Presented in an accessible and introductory manner, this is the first book devoted to the comprehensive study of colloidal suspensions.

The Role of Colloidal Systems in Environmental Protection describes the importance of colloids in many applications that contribute to environmental protection, including drinking water and wastewater treatment, heavy metal remediation, treatment of radioactive materials, corrosion, and energy conversion. Knowledge of the physical and chemical composition of colloids is important to understand and accurately model the relevant processes. The book familiarizes the reader with the technological features of the application of colloids in environmental protection, and provides chemical engineers, researchers, and scientists in academic and corporate communities with the latest developments in this field. Each chapter covers the whole spectrum of the relevant science, from the fundamentals to applications. - Provides the applied technological features of colloids in environmental protection - Gives insight into the use of bio-solid colloids as contaminant carriers - Covers the natural occurrence of biosurfactants in the environment and their applications - Provides information on the use of nanoparticles for environmental applications - Chapters written by recognized and respected experts in the field from all over the world

This book addresses the properties of particles in colloidal suspensions. It has a focus on particle aggregates and the dependency of their physical behaviour on morphological parameters. For this purpose, relevant theories and methodological tools are reviewed and applied to selected examples. The book is divided into four main chapters. The first of them introduces important measurement techniques for the determination of particle size and interfacial properties in colloidal suspensions. A further chapter is devoted to the physico-chemical properties of colloidal particles—highlighting the interfacial phenomena and the corresponding interactions between particles. The book’s central chapter examines the structure-property relations of colloidal aggregates. This comprises concepts to quantify size and structure of aggregates, models and numerical tools for calculating the (light) scattering and hydrodynamic properties of aggregates, and a discussion on van-der-Waals and double layer interactions between aggregates. It is illustrated how such knowledge may significantly enhance the characterisation of colloidal suspensions. The final part of the book refers to the information, ideas and concepts already presented in order to address technical aspects of the preparation of colloidal suspensions—in particular the performance of relevant dispersion techniques and the stability of colloidal suspensions.
